FUEL-ECONOMIZING DEVICE.

Application filed October 14, 1916.

To all whom it may concern:

Be it known that I, OsoAR L. CALLAHAN, a citizen of the United States,residing at Carterville, in the county of Williamson and State ofIllinois, have invented new and useful Improvements in Fuel-EconomizingDevices, of which the following is a specification.

This invention relates to fuel economizing devices for internalcombustion engines, the object in view being to provide means applicableto carburetors already in use whereby a material saving in fuel iseffected, and whereby also the car will be caused to operate withgreater smoothness, will start easier in cold weather, and whereby alsothe accumulation of carbon will be partially eliminated andcorrespondingly increased power and efficiency imparted tothe engine.

With the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts, hereindescribed, illustrated and claimed.

In the accompanying drawing Figure 1 is a plan view of a carbureterequipped with the present invention.

Fig. 2 is a side elevation thereof also showing a. portion of the intakemanifold.

*ig. 3 is a face view of the extension fitting, partly in section.

Fig. 4 is a detail perspective view of the rotary breaker.

Fig. 5 is a similar view of the needle valve arm.

Fig. 6 is a similar view of the throttle valve arm.

A designates generally a carbureter body, 1 the outlet neck thereof, 2the throttle valve operating arm, and 3 the stem of the needle valve bymeans of which the flow of gasolene or other fuel is regulated withinthe carbureter.

In carrying out this invention, I employ an extension fitting designatedgenerally at B and comprising a casing 4 whlch is somewhat elliptical inshape and which corresponds with the shape of the flange 5 ofthecarbureter body, by which the'carbureter is ordinarily fastened to asimilar flange 6 at the receiving end of the intake pipe or mamfold 7.

The casing of the extension fitting is formed with a bore or cylindricalchamber 8 corresponding in size with and also in alinement with theoutlet orifice of the carbureter Specification of Letters Eatent.

proper. Within the chamber or bore 8 is a rotary breaker comprising apreferably vertlcal shaft 9 and upper and lower sets of Wings or blades10 and 11 radiating therefrom, the upper blades extending preferably atright angles to the lower blades and all of the blades having theirouter edges curved to conform and operate in close proximity to the wallof the cylindrical chamber 8; The extension fitting, as shown, is heldfixedly between the flange of the carburetor and the flange of theintake manifold and is formed with a downwardly extending openmgintersecting the cylindrical chamber 8 and having in connectiontherewith an auxiliary air inlet valve comprising a valve chamber 12havin an inlet port-13, a valve 15 Working wit in said chamber and beingpressed against the valve seat 16 by means of a spring 17. The valve isprovided with.

a stem 18 which extends through the deta'chthrottle valve is an arm 21and secured to i the stem of the needle valve is another arm 22 formedwith a longitudinal slot 23 to receive the clamping bolt or screw 24 ofa clip 25 which is thus adjustable longitudinally of the arm on theneedle valve stem. A lin 26 has a pivotal connection with the arm of thethrottle valve and with said clip on the arm of the needle valve. Thesearms are so arrangedthat when the throttle valve is moved toward theopen position, the needle valve is also turned in a direction to effecta further opening of the needle valve to admit a larger proportion ofliquid fuel. The cli on the arm of theneedle valve is made a'd]ustabletoward and away from the stem of the needle valve in order to providefor in the operation of the engine, due to the fact that the air andfuel are mixed in the proper proportions at diflerent engine speeds andthat the mixture is thoroughly churned and broken up or atomized beforeentering the intake manifold of the engine. Further enconomy is broughtabout by the use of the auxillary automatic air intake valveused inconjunction with the casing of the extension fitting in which the rotarybreaker operates. The parts comprised in the present invention may bereadily applied to carbureters now in use, being applicable to thecarbureter without necessitatlng any changes or alterations therein.

Changes in the form, proportion and minor details of "COIIStiIICtIOIimay be resorted to without departing from the principle or sacrificingany of the advantages of the invention.

I claim An extension fitting insertible between connecting flanges of acarbureter and intake pi e, said fitting being formed with a cylindricalchamberadapted to register with the outlet orifice of the carbureter,and a rotary winged breaker journaled in said chamber and embodying arotary shaft extending diametrically of said chamber, said fitting beingformed with an air inlet openin discharging through theperipheral wall 0said chamber and arranged to direct air against the wings of said rotarybreaker for imparting motion to the latter.

In testimony whereof I aflix my signature.

OSCAR 'L. CALLAHAN.
